8dB FM IBOC hybrid injector
The CD324-8DB is intended for use by FM radio facilities increasing IBOC injection to -14dB (4 percent). Its design is based on the field-proven 10dB FM IBOC hybrid combiner used extensively in early IBOC FM field trials. By reducing the coupling level to 8dB the amount of digital power lost to the system reject load is reduced, while the analog power loss increases slightly. The 8dB Injector Hybrid is intended for those FM facilities running at low transmitter power levels and have an interest in increasing their IBOC effective radiate power level to the recently authorized -14dB power level.
